Gumball question

Is there any way to make the space at the center of the axis of the gumball larger?
I can see how to extend the length of the axis and the size of the arrows but the space at the center is too small for me. Often when I’m trying to select a control point or something similarly small, I end up selecting one of the axis.

Thanks in advance for any input you’ve got.

This is a bug. The only help is enlarging the entire gumball by changing gumball radius in the advanced options.
